Understanding Nuclei Interactions: Strength of Strong and Weak Forces on Protons

[Flavia]

Both the strong and weak interactions are short range forces of approximately 1 fm.
Two protons are separated by this distance.

Which equation should i use for these two question?

i) The strength of the electrical and gravitational interactions that influence each of
these protons.
ii) The approximate strength of the strong interaction and the weak interaction on each
of these protons.

 

[Simon Bridge]

(i) use the equations for gravitational and electrical force.
(ii) use equations for strong and weak interactions respectively.
... I don't see the confusion here: you will have been given all four during your studies so far.
